How do you mend a damaged shutter staple? To start, pull out the broken staple from the louver with a pair of needle-nose pliers. Then use some adhesive (like wood glue or epoxy) to cover the legs of a new staple. guide the staple through the loop on the louver and guide its legs into the existing staple holes on the tilt rod. For extra shutter staples, call us at 980-292-3933.
